Not sure if this applies to your question, but depending on when the delay occurs, you could be entitled to a free flight change. Like, if you receive an email the day before the flight saying that it's been pushed back by more than 90 minutes, most airlines will accomodate a flight change.

Source: Has happened to me twice. Got emails saying my flight departure times were changed by more than 90 minutes, called airline, got on different flights for free.

HIIT cardio every morning. (This is too much for most people IMO, and definitely not if you’re not doing something more extreme like prepping for a show). I would suggest 3-4 times a week max.
I also did planks every day, and I think this helped a lot in my overall core development.

For my supps - I was pretty basic. I took Epiburn Pro as my fat burner for about 2 months, and other than that, it was basic supps like protein (usually ON or cellucor), BCAAs (USP Labs Modern BCAA - Grape Bubblegum - yum!), a good multi, fish oil, milk thistle, biotin and Vitamin C. I didn't get sick or even really fatigued all prep. I also took Nitrix for the first 6 weeks or so, but that stuff is hella expensive for what it is and honestly, I didn't see much from it, so I nixed it after that and don't regret it. Peak week, I took Expel as well.

The supps were something I think I could have done better. What would you suggest adding to my list?

Yeah, people are being crazy negative and asshats about it, and I've honestly just stopped checking it. I know how much work this was, day in and day out, meal after meal, lift after lift, and I'm definitely not going to let some internet trolls take away any of my enjoyment of what I've done.

This extreme level of dedication isn't for everyday life. I actually wouldn't recommend making progress this quickly, because it may not be sustainable for everyone! SO don't feel bad and keep doing what you're doing because progress is progress! And thank you for the compliment!

I would LOVE to add some size to my glutes/hams. Seeing myself compared to other competitors made me really how lean I was, and that I should have focused more on leg development. Definitely a goal of mine this offseason...in addition to eating ALL OF THE FOOD. Jk, not really.

I actually did not do much LISS throughout this process. I stuck mostly to HIIT, which I did every morning on an empty stomach. I would lift after work, so around 5 pm or so. I did some LISS for a few weeks in the afternoon on my lunch break, but I stopped that pretty quickly because I was leaning out TOO much.

My biggest recommendation would be to do HIIT 3-4 times a week in the morning if you can. There's a lot of argument that timing doesn't matter, so I can only speak from personal experience, but I think fasted HIIT cardio is super beneficial!

Ohhh I know. I have an incredible ability to do almost anything cold turkey, and I just shut my mind off to the food I couldn't have. Part of me things that mental strength of mine makes me made for something like this. Pretty cool to test your mental capability.
